CHANNEL-FLAP-TURNING MACHINE.

Speciacation of Letters Patent.

Patented. Sept. 5, 1908.

Application filed. October 8, 1904. Serial No. 226,8-99.

To all whom it may concern:

Be it known that I, CHARLES P. STANBON, a citizen of the United States, residing at Lynn, in the countyof Essex and State of Massachusetts, have invented certain newl `flap turning-machineswhich are used in the manufacture of boots and shoes to turn over the channel 4flap against the-sole and thereby open up the channel and prepare it for the reception of the stitches or other fastening dvices by which the sole is securedv to the s. oe.

The object of the invention is to improve the construction and mode of operation of' machines of the class referred to andfto in. crease their eiiiciency.

In channel flap turning machines as here.- tofore constructed the feeding of the sole through the machinehas been accomplished by means of a rotatin Work supportupon which the sole rests. n order to cause the work support to feed the Work it` has `been necessary to provide it with a roughened or comprises a Work support upon which that surface of the sole which is uppermost in the grooved surface. The Work su port acts upon that surface of the sole whic is uppermost in the completed shoe, and on account of its corrugated or roughened-.surface often mars and injures thatA portion of the sole which forms the projecting edge in the completed shoe. l

A feature of the present invention contemplates providing a feed Wheel for feeding the,

work which acts .upon the channeled surface" of the sole outside of the li This feeding wheel acts upon that sur ace of the sole which is lowerms't in the completed shoe, andrupon a portion which is covered by the channel Hap when the flap is laid after the sole has been secured yto the shoe. The wheel can thus be provided with a corrugated or grooved surface so as to positively engage and feed the work and thereby artly or wholly relieve the work support fiom performing the feeding function.' The use of this feed wheel tends to prevent the work support from marring the ltpper surface of the edge of the sole, even when the surface of the work support is roughen'ed or corrugated. It also allows the use o a work support previded with a smooth surface, and such a Work support is preferabl employed'.

Other features o* the present invention relate to' certain improvements in the channel. flap turning tool or wiper, and in the means for mounting the same, to an improved channel opening tool, and its means of support and adjustment, and to an irnproved edge gage.

These features of invention consist in certain devices, combinations and arrangements of parts hereinafter described and claimed,

4the advantages of which will be obvious to those skilled in the art.

The various features of the present invention will be clearly understood from an inspection of the accompanying drawings, in which is illustrated a channe flap turning machine embodying the same in their pireferred form. Referring to the ,drawings-Iigure .l is a longitudinal sectional view of this machine,- the driving shaft and a portion of the frame at the rear of the machine supporting the same being omitted.y Fig. 2 is a view in front elevation of so much of the machine as is illustrated in Fig. l, and Fig. 3 is a sectional plan view of the front portion of the machine taken. on a.

Iplane indicated b the line 3*-3 on Fig. l.

'The machine i ustrated in the drawings com leted shoe rests, an edge gage against flap over against the surface of the sole, al

feedin wheel which bears uponthe channeled sur ace 'of the sole outside of the channel flap, and a presser foot which bears upon the channel iiap after it ha's been 'turned over against the surface of the sole by the hap turning wheel. l

The work support is indicated at 1 and as illustrated is frusto conical in shape and rovided with a smooth work-engaging surace. The work support is secured u on the outer. end of a shaft 2 'ournaled in a lock 3 and free ,to slide'longitudinally in its bearings. Thej rear end of' the `'shaft 2 is oonnected b a universal jointr to a shaft e journaled in earings in the frame Io f the machine -35 cut inthe slide.

its rear end with a screw-threaded opening .which is engaged by the split end of a'rod 14.

40 of the machine, an

and this shaft is provided at its rear end with a gear wheel to which is secured a belt pulley 6. The pulley 6 is driven by means of a belt from the driving shaft of the machine,

5 and through the shafts 4 and 2 imparts a constant rotation to the work" support 1 in a direction to feed the work through the ina chine.

The block 3 is pivotally supported in a 1o slide 7 mounted in a vertical guideway in `the front .portion of the machine frame. .'l his slide isipressed upwardly by a coiled spring 8 interposed between the slide and a sleeve 9 having a screw-threaded engagement with .a

l5 projection at the base portion of the frame of the machine. The spring 8 forces the slide 7 upwardly and holds the work support yieldingly in position during the channel opening and flap turning operations- In order to to allow the work support to be depressed when work is to be inserted in the machine,

the slide 7 is connected toa rod 10 which extends through the spring 8 and sleeve 9, and

which is connected in any suitable manner to a foot treadle.

i The edge guide against which th'e edge of the sole bears as it is fed Ithrough the machine is indicated at 11, and as shown consists of a roller mounted to rotate eely upon a stud secured 'tothe front end of a" horizontal slide 12. The slide 12 is cylindrical and is mounted ina cylindrical guideway in the frame of the machine, being prevented from turning by meansof a screw 13 which engages a groove The slide 12 is provided at This rod extends. through a sleeve 15 having a'screw-threaded ven agement with the frame at its rear' 3nd is pro- 'videdxwith a head which 'bears against the lrear end of the sleeve. i

around the rod 14 and interposed between I the adjacent ends of the slide 12 `and sleeve "-15.A The edge gage 11 is thus yieldingly mountedy so that-it is capable' of moving in the plane of the sole transversely to the line 'of feed. The initial position ofthe edge gage ',can be adjustedby adjustingt'he sleeve 15,

and it will be seen thatthis adjustment does not alter the tension' of the spring '16.

' As the sole vpasses through the machine itv is first acted upon by a `channel o ening tool which is indicated at 17 As s own, this tool consists of a'roller proyided with a flan e at its lower end and mounted tofrotate free y upon a vstud secured in the forward end of a uresilient arm or spring plate 18. The channel opening tool is thus yieldingly mounted :6.0 so as tol be 'capable of moving in a direction substantially perpendicular to the surface of the sole, and can accommodate vitself to any variations in the thickness of the stock or in the depth of the channel. The channel opening tool can be adjusted'vertically or .in .a

The arm is securely clamped in its adjusted position by clamping screws 21, best shown in Fi 3. After the channel fla has been turned into a substantially verticalpposition by the channel opening tool, it. is engaged -by a lap turning wheel orwi er indicated at 22. This flap turning whee is mounted to rotate upon an axis substantiallyv parallelwith the surface of the sole and its periphery is grooved 35 to form al series of projections, whichduring the rotation .of the wheel wi e transversely across the channel flap# an vturn it over against the surface of the solei The grooves vin the peripheryof the flap turning'wheel are 90 preferably inclined, as fn icated in Fig'. 2, so that the periphery of the wheel has an appearancesomewhatsimilar to that'of a worin gear, andthe projections on the eri hery of thewheel acttofim el the lwork in t e direction of the feedf-fg-'llhe stud upon which the apturniiigwheel is mounted is secured in a frame 23 mountedupon the upper portion Nof the main frame ,1o-fthe machine so as to be casubstantially perpendicular to the surface of the soleA r""'ii`h'e' vertical adjustment of the fraine23 isaccomplished by means of an adjusting screw 24 which assesthrough a lug on the upper ortion oft e main frame of the machine fan screws into the frame 23, a

The fia turning wheel is rotated constantly in a direction to turn the channeliap over against the' surface of the sole by meansv of a belt 27 which is' driven from a pulley on the main driving shaft and which asses beneath an idle pulley 28 and aroun a pulley 29 rigid with the flap1 turning wheel. A guard 30 is secured to t eframe 23 and rejects over a portion of the periphery of tfie flap turning 125 wheel so as to protect the operator from' injury. g After the ilap has been turned over against the sole by the fia turning'wheel .it passes beneath a presser fil ot indicated at 31 which 136 er to provide 7g) irons down the iiap and sets it in the position to which it has been turned by the Wheel. rl`his presser foot, as shown, consists of a plate secured by aclamp on the upper end of a vertical slide 32, the construction of the clamp being such that the presser foot can be adjusted transversely to the direction of feed, as is clearly shown inllig. 3. The slide 32 rests upon a set screw 33, by means of which the slide and the presser foot carried thereby cany be adjusted vertically to cause the presser' foot to exert the required amount of lpressure on the channel flap. The slide is he d in its adjusted position by clamping :screws 34.

The feed Wheel Which engages the channeled surface of the sole outside of the channeliiap is indicated at 35. As showin-this Wheel is provided With a roughened or grooved surface so as to positively engage the Work and feed it With certainty through the The Wheel is arranged at one side of the flapturning wheel so that it acts upon the sole after the channel liiap has been turned over. The Wheel can be arranged to act in the .channel so that the surface acted upon by the Wheel is covered by the channel flap in the completed shoe.

A constant rotation in a'direction to cause the work to be fed through the machine is imparted to the Wheel from the-gear 5 on the shaft 4 which meshes with a pinion 36 fast upon a sleeve 37 rigidly secured to the shaft 38,/upon the forward end of which the feeding wheel is mounted. The sleeve 37 is mounted to rotate in a bearing in theI rear portion of the machine frame.

' end of the shaft 38 is journaled to rotate in a bearing in the front'portion of the machine frame, and can slide longitudinally in its bearing. The rear end ofthe shaft-38 has a screw-threaded engagement with the sleeve 37 and is locked to the sleeve by means of a locking nut 39. Provision is thus made for adjusting the feeding Wheel in the plane of the sole transversely to the directionof feed so that the Wheel can be. brought-intesa position to act to the best advantage on different styles of work. j j
